Direct labelling in plots

Hi. How can I put direct labelling into the graph? Like in the below figure, the name of continent must appear next to the line representing the respective continent.

#> Attaching package: 'janitor'
#> The following objects are masked from 'package:stats':
#>     chisq.test, fisher.test

gapminder<-gapminder %>% 

gapminder %>% 
  group_by(continent,year) %>% 
  summarise(mean_life_exp=mean(life_exp)) %>% 
  labs(title="Trend in life expectancy across continents",x="Year",ÿ="Average Life Expectancy")
#> `summarise()` has grouped output by 'continent'. You can override using the `.groups` argument.

like this?

# Data for the plot 
plot_gapminder = gapminder %>% 
  group_by(continent,year) %>% 

# find the max points for the text labels
text_gapminder = plot_gapminder %>% 
  summarise(year = max(year),
            life_exp = max(mean_life_exp))

ggplot(plot_gapminder) +
  labs(title="Trend in life expectancy across continents",
       x="Year", y="Average Life Expectancy") +
  geom_text(data = text_gapminder,
            aes(x = year+1, # adding some offset  
                y = life_exp, 
                label = continent, colour = continent),
            size = 5,
            hjust = 0) +  
  coord_cartesian(xlim = c(1950, 2012)) + # you may need to adjust this a bit
  theme(legend.position = "none")

Thank you for this. It is as per requirements.
